executed for all volumes in the group, and all inconsistent volumes are
found in the execution log file and displayed (same as paircurchk
command).
The horctakeover command allows swapping of the primary and secondary
volumes, so that if the primary or secondary volume is switched due to a
server error or package transfer, duplex operations can be continued using
the reversed volumes. When control is handed over to the current node,
swapping the volumes again deletes the need to copy them. The
horctakeover command also allows the secondary volume to be separated
for disaster recovery operations.

lists and describes the TrueCopy or TCE horctakeover command
horctakeover
horctakeover { -h  -q  -z  -I[H  M][instance#]  -g group  -d pair Vol

-h: Displays help, usage, and version information.
-q: Terminates the interactive mode and exits the command.
-z or -zx: Makes the raidscan command enter the interactive mode. The -zx
option guards performing of the HORCM in the interactive mode. When this
option detects a HORCM shut down, interactive mode terminates.
-I[H | M][instance#] or -I[TC | SI][instance#]: Specifies the instance
number and the command execution environment. Refer to
and option for command execution environment on page
-g <group>: Specifies the group name defined in the configuration definition
file. This option must always be specified. The command is executed for the
specified group unless the -d <pair Vol> option is specified.
-d <pair Vol>: This option is used to specify the paired logical volume name
defined in the configuration definition file. When this option is specified, the
command is executed for the specified paired logical volumes.
-d[g] <raw_device> [MU#]: Searches a group on the configuration
definition file (local instance) for the specified raw_device, and if the specified
raw_device is contained in the group, the target volume is executed as the
paired logical volume (-d) or group (-dg). This option is effective without
specification of "-g <group> " option. If the specified the raw_device is
contained in two or more groups, the command is executed on the first group.
-d[g] <seq#> <LDEV#> [MU#]: Searches a group on the configuration
definition file (local instance) for the specified LDEV, and if the specified LDEV
is contained in the group, the target volume is executed as the paired logical
volume (-d) or group (-dg). This option is effective without specification of "-
g <group> " option. If the specified LDEV is contained in two or more groups,
the command is executed on the first group. The <seq #> <LDEV #> values
can be specified in hexadecimal (by addition of "0x ") or decimal notation.
-S: Selects and executes SVOL-takeover. The target volume of the local host
must be an S-VOL. If this option is specified, then the following "-l" option is
invalid.
